What kind of waves vibrate our eardrums so we are able to listen?Radio wavesSound wavesLight wavesMicrowaves

To understand what kind of waves vibrate our eardrums and allow us to hear, we need to look at the characteristics of each option provided:

1. Radio Waves: These are electromagnetic waves typically used for communication and broadcasting. Their wavelengths are much longer than those of sound waves, and they do not cause vibrations in our eardrums.

2. Sound Waves: These are mechanical waves that require a medium (such as air, water, or solids) to travel. Sound waves cause the particles of the medium to vibrate, which in turn vibrates the eardrums when sound is produced. This is the primary way we perceive sound.

3. Light Waves: Like radio waves, light waves are also electromagnetic waves. They can be detected by our eyes, but they do not interact with our eardrums in a way that produces sound.

4. Microwaves: These are another form of electromagnetic radiation, primarily used in cooking and communication. They do not vibrate the eardrums or produce sound.

Conclusion

The correct answer is Sound Waves. They are the only type of waves listed that directly vibrate our eardrums, allowing us to perceive sound.
